摘　　要：本文研究发现,在江苏发生于乌蔹莓上的一种天敌条纹小斑蛾Thyrassia penangae Moore被误定为乌蔹莓鹿蛾Amatasp.,并在乌蔹莓上首次鉴定出了广鹿蛾Amata emma(Butler)。条纹小斑蛾(乌蔹莓鹿蛾)与广鹿蛾外形很相似,容易混淆。本文通过比较形态学方法,明确了两者的鉴别特征。前翅基部有无黄色纵条纹是区分两种的主要外形特征,并列出了它们在触角和雌雄外生殖器上的区别特征。研究结果为进一步厘清两种相似蛾类各自的生物学特性提供了科学依据。It was found that Thyrassia penangae Moore had been misidentified as Amatasp.and Amata emma（Butler）was firstly recognized to attack Cayratia japonica（Thunb.）in Jiangsu Province.T.penangae and A.emma are very similar in the superficial characters.This paper deals with the diagnostic morphological characters for identification of the two species by comparative morphology methods.The forewing with a longitudinal stripe at the base is an obvious character to distinguish T.penangae from A.emma.The diagnostic characters of the antenna and genitalia are also provided.The results provide the basic information for revising the biological characteristics of the two similar moths.
